determine_absolute_timing(schedule: quantify_scheduler.schedules.schedule.Schedule, time_unit: Literal[physical, ideal] = 'physical') → quantify_scheduler.schedules.schedule.Schedule[source]

Determines the absolute timing of a schedule based on the timing constraints.

This function determines absolute timings for every operation in the schedulables. It does this by:

  1. iterating over all and elements in the schedulables.

  2. determining the absolute time of the reference operation.

  3. determining the start of the operation based on the rel_time and duration of operations.

Parameters

  • schedule – The schedule for which to determine timings.

  • time_unit – Whether to use physical units to determine the absolute time or ideal time. When time_unit == 'physical' the duration attribute is used. When time_unit == 'ideal' the duration attribute is ignored and treated as if it is 1.

Returns

a new schedule object where the absolute time for each operation has been determined.

_find_edge(device_cfg, q0, q1, op_name)[source]
add_pulse_information_transmon(schedule: quantify_scheduler.schedules.schedule.Schedule, device_cfg: dict) → quantify_scheduler.schedules.schedule.Schedule[source]

Adds pulse information specified in the device config to the schedule.

Parameters

  • schedule – The schedule for which to add pulse information.

  • device_cfg – A dictionary specifying the required pulse information.

Returns

a new schedule object where the pulse information has been added.

Supported operations

The following gate type operations are supported by this compilation step.

Configuration specification

validate_config(config: dict, scheme_fn: str) → bool[source]

Validate a configuration using a schema.

Parameters

  • config – The configuration to validate

  • scheme_fn – The name of a json schema in the quantify_scheduler.schemas folder.

Returns

True if valid

qcompile(schedule: quantify_scheduler.schedules.schedule.Schedule, device_cfg: Union[quantify_scheduler.backends.circuit_to_device.DeviceCompilationConfig, dict] = None, hardware_cfg: dict = None) → quantify_scheduler.schedules.schedule.CompiledSchedule[source]

Compile and assemble a Schedule into a CompiledSchedule ready for execution using the InstrumentCoordinator.

Parameters

  • schedule – The schedule to be compiled.

  • device_cfg – Device specific configuration, defines the compilation step from the quantum-circuit layer to the quantum-device layer description.

  • hardware_cfg – Hardware configuration, defines the compilation step from the quantum-device to a hardware layer.

Returns

The prepared schedule if no backend is provided, otherwise whatever object returned by the backend

Configuration specification

Todo

Add a schema for the hardware config.

device_compile(schedule: quantify_scheduler.schedules.schedule.Schedule, device_cfg: Union[quantify_scheduler.backends.circuit_to_device.DeviceCompilationConfig, dict]) → quantify_scheduler.schedules.schedule.Schedule[source]

Add pulse information to operations based on device config file.

Parameters

  • schedule – To be compiled.

  • device_cfg – Device specific configuration, defines the compilation step from the gate-level to the pulse level description.

Returns

The updated schedule.

hardware_compile(schedule: quantify_scheduler.schedules.schedule.Schedule, hardware_cfg: dict) → quantify_scheduler.schedules.schedule.CompiledSchedule[source]

Add compiled instructions to the schedule based on the hardware config file.

Parameters

  • schedule – To be compiled.

  • hardware_cfg – Hardware specific configuration, defines the compilation step from the quantum-device layer to the control-hardware layer.

Returns

The compiled schedule.
